I have no choice because am a girl!

After 3 years of an endless,pure relation with this guy suddenly disappeared from my life because his family thinks am not good for him..If I can stand beside him then why can't he?? He cut off every communication with me..He's not even calling/texting me at all..He's acting as if like he never existed at all!! I told my mom about it.She told me that she would call him but if he still does the same she would forbid me to call or text him and in later after some years she will choose someone for me to marry...

Am not having his support,I still love him deeply..I just wish when my mom will call him,am gonna hear positive news...

Am really breaking into tears...
